All animals, apart from simple invertebrate groups, possess a blood vascular system, which enables the passage of respiratory gases, nutrients, excretory products, and other metabolites into and out of the cells.

What does vascular mean in animals?
Relating to, characterized by, or containing cells or vessels that carry or circulate fluids, such as blood, lymph, or sap, through the body of an animal or plant.
Are humans vascular?
The vascular system, also called the circulatory system, is made up of the vessels that carry blood and lymph through the body. The arteries and veins carry blood throughout the body, delivering oxygen and nutrients to the body tissues and taking away tissue waste matter.
What is vascular system in plants and animals?
A vascular system simply means that it is a system where things are transported in vessels. For plants, it will be the xylem and phloem and for animals, it will be the arteries and veins.
Is circulatory system in animals?
The circulatory system varies from simple systems in invertebrates to more complex systems in vertebrates. The simplest animals, such as the sponges (Porifera) and rotifers (Rotifera), do not need a circulatory system because diffusion allows adequate exchange of water, nutrients, and waste, as well as dissolved gases.
Do aquatic animals have circulatory system?
Animals live in an aquatic environment even on land. Most animals have open circulatory systems. ... Those few animals with closed circulatory systems have a continuous series of vessels to circulate fluid to the vicinity of all cells, whereas those with open systems have vessels only near the heart.
Are all tissues avascular?
Cornea and lens of the eye, cartilage, epithelium of the skin, etc. are examples of avascular tissues. In fact, most tissues in the body are vascular.
What is the largest artery in the body?
Aorta Anatomy
The aorta is the large artery that carries oxygen-rich blood from the left ventricle of the heart to other parts of the body.
Where are all your veins located?
Systemic veins are located throughout the body from the legs up to the neck, including the arms and trunk. They transport deoxygenated blood back to the heart.
What are the animal tissues?
The tissues of multicellular, complex animals are four primary types: epithelial, connective, muscle, and nervous. Recall that tissues are groups of similar cells group of similar cells carrying out related functions.
What is the difference between plant and animal circulatory system?
In mammals this forms a circulatory system of arteries, capillaries and veins. In flowering plants, transport is not circulatory and occurs in microscopic xylem and phloem. ... Both animals and plants have more than one type of tissue which is specialised to make transport an efficient process.
What is the difference between plant circulation and animal circulation?
Animals must have nutrients and oxygen reach every cell in their body. Plants must have nutrients and carbon dioxide reach every cell in their “body.” Both plants and animals must also have waste products removed from their systems. ... Animals can have one of two kinds of circulatory systems: open or closed.
Which animals do not have a circulatory system?
Two animals without blood or circulatory system in their bodies are flatworms and jellyfish. They do not have any fluid in their body as they take in oxygen, nutrients and minerals directly from the air and water.
Do fish have single or double circulation?
Fish have a single systemic circuit for blood, where the heart pumps the blood to the gills to be re-oxygenated (gill circulation), after which the blood flows to the rest of the body and back to the heart.
Do birds have single circulation?
Double circulation pathways are found in birds and mammals. ... These circulatory systems are called 'double' circulatory systems because they are made up of two circuits, referred to as the pulmonary and systemic circulatory systems. Humans, birds, and mammals have a four-chambered heart.
